TB9400 Installation and Operation Manual 123

hysteresis
The difference between the upper and lower trigger points. For example,
the receiver unmutes when the upper trigger point is reached, but will mute
again until the level falls to the lower trigger point. An adequate hysteresis
prevents the receiver gate from repeatedly muting and unmuting when the
level varies around the trigger point.
I
2
C A bi-directional two-wire serial bus which is used to connect integrated
circuits (ICs). I
2
C is a multi-master bus, which means that multiple chips
can be connected to the same bus, and each one can act as a master by
initiating a data transfer. Used in the TB9400 for communications between
reciter 1 and the PMU.
impairment A measure of signal quality used in channel group voting. Impairment is
inversely related to signal quality. The lowest impairment (0) indicates the
highest signal quality. The highest impairment (15) indicates the worst
signal quality.
inbound Describes the direction of a signal: from an SU over the air interface to the
fixed station.
inhibit A control command that can be sent across the CAI to inhibit an SU. An
inhibited SU appears to the user as if it is powered off.
IP Internet Protocol is a protocol for sending data packets between hosts.
isolator A passive two-port device which transmits power in one direction, and
absorbs power in the other direction. It is used in a PA to prevent damage
to the RF circuitry from high reverse power.
kernel The core executable of an operating system.
LAN Local Area Network. A computer network that interconnects computers in
a limited area, such as a single building or group of buildings.
LDU Link Data Unit. Voice calls are sent over the CAI as a series of LDUs.
LED Light Emitting Diode. Also the screen representation of a physical LED.
license Some operational functions of the base station are controlled by licenses.
Purchasing a license from Tait allows you to enable the feature set which
includes the required functionality.
LSM Linear Simulcast Modulation is a proprietary modulation scheme designed
to give optimal performance in simulcast systems, compared to that
obtainable using C4FM.
